Abstract
The invention discloses a tapping screw induction heating coil applicable to a high-speed loading rotary table. The tapping screw induction heating coil applicable to the high-speed loading rotary table comprises a heating coil body, a base, a connecting copper bar, a starting load and copper bar components. The heating coil body is arranged on the base; the connecting copper bar is arranged on the tail part of the heating coil body; the copper bar components are respectively connected with the connecting copper bar and the heating coil body; and the starting load is arranged on the copper bar components. According to the tapping screw induction heating coil applicable to the high-speed loading rotary table provided by the invention, a heating section of the coil body adopts an arc-shaped structure design so as to be matched with a rotary table type automatic high-speed screw induction quenching system, so that the processing limitation of stations is free, the heating process can be carried out coherently, and the production efficiency is improved; and a cross section design of the heating coil produces specific magnetic field distribution, so that a specific heat affected zone is produced on a workpiece to be heat, and the workpiece achieves the mechanical performance meeting the requirement after being quenched.
Description
technical field [0001] The invention relates to a self-tapping screw induction heating coil suitable for a high-speed feeding turntable used in the field of screw manufacturing. Background technique [0002] Screw is a common fastening part, which is widely used in the field of mechanical manufacturing. Bolts used in special environments have special performance requirements, so they need to be heat treated in the production process, so as to enhance the strength, hardness, wear resistance, fatigue strength and toughness of bolts to meet practical requirements. [0003] The traditional self-tapping screw induction heating method is a station work mode, which needs to be manually or mechanically clamped to realize the loading and unloading of fixed stations, which greatly limits the screw processing and production efficiency. In the induction heating and quenching equipment for self-tapping screws with rotary table and automatic continuous feeding, self-tapping screws can ac...
